A:AnswerI've had mine since release date and no issues in either earcups. I'm also on the latest firmware update. You should take yours back and get a refund or replacement if you plan to keep them.
A:AnswerYou might get some sound leak from the headphones depending on how loud your husband turns them up, but for average listening you won't hear what he is listening to
A:AnswerI dont think so. I have a Playbar and the Sonos Ace cannot play audio from the Sonos app. To me, i dont see any benefit of them over ordinary bluetooth headphones such as Bose, Apple, Beats, etc. Maybe they will update?
A:AnswerYes. It came with a wire for this. I used it in one hole of a double hole fitting without any issues. Ace must be charged and powered on though.
A:AnswerSync to phone via bluetooth. Supposedly, it can sync to Sonos Arc, but that feature is called "TV audio Swap" which leads me to believe it will be one or the other, not both simultaneously.
A:AnswerApparently not at launch, and not clear if it will come in the future either...also at launch, the handoff feature will only work with Arc owners using iOS.
